What is a YAG?

A YAG laser capsulotomy is a procedure that is sometimes required after Cataract Surgery. “At least 30% of patients who have cataract surgery will develop a secondary cataract over time and require a YAG laser” says Dr. Jordan Sterrer of Eyecare Medical Group.


When a patient has their natural lens removed during Cataract Surgery, the capsule of the original lens is left intact to support the new intraocular lens that is implanted. Sometimes, a cloud forms in the capsule and vision becomes blurred. This is what is referred to as a secondary Cataract. The procedure to relieve this problem is a YAG laser capsulotomy. A small opening is created in the center of the capsule, and vision is restored. A YAG laser procedure is painless and generally takes about 15 minutes. Because a secondary Cataract does not develop in all patients, a YAG laser procedure is considered a separate procedure from the original Cataract Surgery.
